She said: "Sometimes I have so much sex to try to calm myself down I get bored of it. And men I sleep with don't seem to make as much effort because I climax so easily."

As she chatted, Sarah became increasingly flustered.

"Sorry, you'll have to excuse me for a minute. I'll be with you in a sec," she mumbled before letting out a long sigh.

Sarah, from London, developed PSAS after being prescribed anti-depressants at 19."

...

"She explained: "Anything can set me off. Even the hairdryers cause funny pulsations through my body.

"As a skin care specialist I have to use tools which vibrate a lot of the time for micro-dermabrasion and they sometimes set me off.

"I find if I'm nervous I'm less likely to get over-excited. So sometimes I try to psyche myself up and worry to control my orgasms.

"Some of my regular customers know my problem. But with new clients it's hard to explain.

"I have been in the middle of a treatment and it's happened and I've had to carry on.

"I was doing a bikini wax and you have to really concentrate and keep your hands very still, and mine go a bit wobbly when I orgasm. "

The touchy subject has kept her smiling.

Needless to say, the condition has not proved beneficial to the dating game. The men can't seem to do as well as her imagination, which causes a orgasm every time she thins about sex, which appears to be about 200 times a day according the DBKP mathematicians..

'It has proved to be a problem for Sarah in some relationships.

She said: "I dated one guy who was very selfish and he was that way in the bedroom too. He'd just lie back and expect me to please him.

"He just figured that because I could climax without him even having to touch me, he didn't need to do anything to please me.

"I just thought that was rude and inconsiderate. It didn't last very long with him."

Sarah does not share.

"With me, it was a means of releasing my orgasm, but now I know I don't have to have sex to do that."

Now many might think moaning in public while staring at a movie poster,riding a train, or doing a bikini wax, is a rather uncomfortable way to go through life. And the solution appears simple enough. Since Sarah's condition is caused by a sharp , permanent, increase in blood flow to the genitalia, that the simple thing to do would be to alter the anti-depressant prescription.

Ahh. Not a chance.

"Thanks to her understanding friends and colleagues, Sarah feels like she can now live with PSAS.

""I'm lucky because people around me are very kind and appreciate that sometimes this is a problem for me and it can be embarrassing."'

Sarah said in a high pitched yelp, trying to suppress a smile.

Oh, and certain members of the editorial board her a DBKP have a question.
